CHARLES WVAYTE, OF EPSOM, COUNTY OF SURREY, ENGLAND.

AUTOMATIC VENT-PEG.

SPECIFICATION forming part of Letters Patent No. 425,530, dated April15, 1890.

Application filed December 12, 1889. Serial No. 333,416. (No model.)Patented in England September 6, 1887, No. 12,068.

To aZZ whom it may concern:

Be it known that I, CHARLES WAYTE, a subject of the Queen of GreatBritain, residingat Epsom, in the county of Surrey, England, haveinvented a new and useful Improved Automatic Vent-Peg, (for which I haveobtained a patent in Great Britain, No. 12,068, dated September 6,1887,) of which the following is aspecification.

This invention relates to an inexpensive aultomatic ventpeg for casksand other vesse s.

In carrying out my invention I make use of an india-rubber or otherelastic tube having one or more slits formed therein and containing acore secured to the lower end of such tube and extending above saidslits, so'that air can pass from the exterior of the cask between thecore and the tube through the slits, but that the pressure Within thecask or other vessel will press the said tube into close contact withthe core and prevent the egress of gas.

In order to enable my invention to be fully understood, I will describehow it can be carried into practice, by reference to the accompanyingdrawings, in which- Figures 1 and 2 are elevations, and Fig. 3 1s asection. of an automatic vent-peg constructed according to my inventionand shown inserted in the usual spile-hole of a cask, a portion of oneof the staves of which is represented in section. Figs. 1 and 3represent the valve of the ventepeg in its normal or closed position,and Fig. 2 shows the valve open. Fig. at is a similar view to Fig. 3,but showing a modified arrangement of my improved vent-peg.

Similar letters in all the figures indicate similar parts.

a. is a hollow metal cone provided with wings I) 1), whereby it can beforced into and removed from the vent-hole of the cask U.

o is the piece of elastic tube which I fit over.

the smaller end of the cone.

d cl are the slits or incisions in the tube a, which is closed upair-tight at its lower end by being bound to a piece of india-rubber,wire, or an equivalent core e introduced into the elastic tube, whichthus forms a kind of valve.

From the foregoing description it will be easily understood that thevalve will prevent the gas from escaping through the vent-peg,

but when the liquid is withdrawn from the cask the air will enterthrough the slits or incisions (1 din the elastic tube 0, which, underthe pressure of the said air, will open somewhat in the manner shown inFig. 2.

In the modified arrangement shown in Fig. 4 I slit the hollow metal conea downward from the top in three or four places, so that the upper partof the cone, which projects beyond the cask after the cone has beendriven in, can be laid over upon the cask. The portions Ct at of thecone formed by slitting the same can be used to extract the peg by meansof a pair of pliers or the like, when required to be replaced by a newone. The piece of elastic tube 0 is placed over the smaller end of thecone and made air-tight at its end, as hereinbefore described.

This peg will not ofier any obstacle to the cask being rolled about, andthe valve will prevent the liquid from escaping. The peg having beenonce inserted will last for months, as the cask can be washed outwithout risk of injury to the peg. It will be obvious that a similarresult can be attained by inserting in the cone a valve which is broughtto its seat by means of an elastic substance, such as india-rubber fiberor thread.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is l. A vent-peg adapted for a seat in a cask, and havingan elastic tube projecting from its inner end and made with slitstherein, and also having a core-piece secured to the extremity of suchtube and extending back beyond such slitted portion, as shown anddescribed.

2. A vent-peg for casks, having a tube held by its own elasticity uponand projecting from its inner end and having slits or incisions therein,and havinga core-piece secured to the other end of such tube andextending back beyond such slitted portion, the peg being also providedwith wings Z), all as and for the purposes set forth.
